Have you ever successfully raised a social parasite? And if so how did you do it because I heard it was super difficult

Social parasites are different depending on the genus and species, and I've had multiple successes with both Lasius and Formica social parasites. Formica are easy, because they can open cocoons, although the raiding species are often dependent on their host workers over the long term.

I've started colonies of Formica aserva, Formica rubicunda, Lasius umbratus, Lasius subumbratus, and (waiting on the first workers) Lasius latipes.

Is it okay to have them in the containers they are in? I don't have any test tubes.

It's okay to put them in containers as long as you have cotton inside and you always keep it moist and wet,NEVER LEAVE IT DRY![use a pipette to make the cotton moist]
Also try to keep them in the dark;)
